Analysis and solution of the light and radial velocity curves of the contact binary TY Bootis
Observations and analyses of the binary TY Bootis are presented. Radialvelocity data are used for the first time to establish the mass ratiowithout ambiguity, and an advanced version of the Wilson-Devinneysynthetic light curve program is used to analyze and solve the system. Areasonably robust set of parameters is obtained. TY Boo is found to be aW-type W UMa system with a mass ratio near two and a contact parameterof 0.12 + or - 0.903, indicating only shallow contact.
